Effects of temperature on yield, fruit shape, and flower primordium development of bell pepper (Capsicum annuum L.)
Two years of field studies were conducted to evaluate effects of spunbonded polypropylene row cover removal time on growth, yields, and fruit shape and size of bell pepper. Vegetative growth of bell pepper increased under row covers, and plant fresh weight was positively correlated with the …

Exploring the transcriptomic landscape of the Drosophila melanogaster embryonic salivary gland.
… patterning of genes within the salivary gland primordium prior to morphogenesis makes the Drosophila melanogaster embryonic salivary gland an excellent candidate for single cell RNA sequencing to identify novel genes involved in the process of tube budding and to delineate their order of …

Investigating the Supracellular Processes Underlying Emergent Material Phase Properties During Embryonic Skin Morphogenesis
… changes that initiate the feather follicle primordium gene expression program. Yet, two questions remained. How do cells coordinate and tune their mechanical forces across a field of cells in order to generate the correct pattern? Once the dermal condensate forms, what role do molecular …

Phytohormones and the Culture of Agaricus bisporus (Lange) Pilat
… phytohormones to malt extract agar accelerated primordium initiation and significantly increased number over the control . Compost and casing soil contained appreciable amounts of the three groups of phytohormones (auxins, gibberellins and cytokinins). The fluctuation in levels of phytohormones …

The role of pou2/spiel-ohne-grenzen (spg) in brain and endoderm development of the zebrafish, Danio rerio
… to activate genes of the MHB and hindbrain primordium, like pax2.1, wnt1, gbx2 or krox20. By gain-of-function experiments I demonstrate that pou2 synergizes with Fgf8 signaling in order to activate particularly the hindbrain primordium. Since pou2 is already provided to the embryo by the …

The effect of the CCI mutation on cell cycle morphogenesis in Paramecium Tetraurelia
… to division, which occurs at the 6-rowed oral primordium stage. At this stage micronuclei are in late anaphase. Oral morphogenesis is arrested up to this stage in mutant cells at the restrictive temperature, as are later stages of micronuclear division. These results are interesting because …

Aportación a la morfogénesis encefálica en los horizontes XVI y XX de la clasificación de Streeter
… foramen interventricular. 11. Ha aparecido el primordium hippocampi dorsal a los plexos coroideos y resaltando en los ventrículos laterales. 12. En el horizonte XX puede reconocerse el primordium del bulbo olfatorio. B) DIENCEPHALON 13. En el horizonte XX aparee el sulcus medius, y contribuye …

Characterization of split ends function during Drosophila eye development
… that passes through the imaginal disc eye primordium, Notch signaling is required for establishing and refining the expression of proneural Atonal (Ato). Ato promotes the EGFR pathway's reiterative signaling for progressive and sequential recruitment of cells within each ommatidial facet of …

Regulation of the development and regeneration of the zebrafish posterior lateral line
… migration of the posterior lateral line primordium, but no changes in proliferation. To better characterize the function and effect YEATS2 mutations have on LL development we generated a CRISPR/Cas9 mutant line, yeats2ᴬᵀᴳ, that recapitulates the yeats2ⁿˡ²⁴ phenotype. These reduced cell …

The role of expansin in leaf development: A molecular genetics and AFM approach
… I describe the use of AFM for probing the leaf primordium mechanics and outline consideration for future work.

Physiological Studies on the Growth and Fructification of the Edible Basidiomycete Series, Pleurotus Sajor-Caju (Fr.) Sing. and Stropharia Rugoso-Annulata Farl. ap. Murr.
… species. While P.sajor-caju required light for primordium formation and fruit-body development, S.rugoso-annulata appeared to be indifferent to light. P.sajor-caju showed no need for a casing layer to fructify. In contrast, S.rugoso-annulata required casing soil for fruit-body formation. The …

Functional Characterization of a Cathepsin L in Drosophila Melanogaster
<p>The Drosophila dorsal Air Sac Primordium (ASP) is a tracheal tube that invasively grows toward and into the wing imaginal disc. The unfolding of Drosophila wing is a process following eclosion with a cuticular bilayer replacing epithelial cells originally packing the wing. We reasoned that …

Distinct Functional Properties of Perinatal Versus Adult Adipose Progenitor Subpopulations
… of the perinatal murine epididymal WAT (eWAT) primordium. I reveal that adipocyte precursor cells (APCs) and fibro-inflammatory progenitors (FIPs) emerge as functionally distinct PDGFRb+ subpopulations within the eWAT anlagen prior to adipocyte accrual, at postnatal day 3 (P3). Importantly, I …

The role of the transcription factor JAGGED in early floral organogenesis
… for the transition from meristematic to organ primordium cell behaviour. The transition involves an increase in the rates of cell division and cell growth, a shift from isotropic to anisotropic growth, and modifications in cell size homeostasis in primordia (Schiessl et al., 2012). In this …

Identifying the mechanism critical for proliferation, apoptosis, and cell-cell interaction in the development of mouse adrenals and gonads
… are steroidogenic organs derived from a common primordium that consists of Steroidogenic factor 1 (SF1)-positive precursor cells. SF1 not only defines the steroidogenic lineages in these organs, but also controls their differentiation. In this thesis project, I used Sf1/Cre transgenic mice to …

Regeneration and maintenance of the planarian nervous system

The mechanical regulation of Semaphorin3A signalling in the developing Xenopus laevis brain
… for compliant gel fabrication and Xenopus eye primordium dissection. I re-established optical membrane potential recording of Xenopus axons, replicating the finding that axons on soft gels are more depolarised than on stiff gels. To develop a Piezo1 knockdown model complimentary to the …

THE IN-VIVO IMPACT OF SMPX MUTATIONS DURING DEVELOPMENT AND DISEASE

Morphogenesis and Female Fate Determination in Vertebrates
… testis and the ovary, from a single bipotential primordium. The outcome of this decision, which is made by a population of somatic cells known as the bipotential supporting cell precursors, determines whether an embryo will develop as a phenotypic male or female. Though several molecular pathways …

The development and evolution of vertebrate oxygen-sensing cells
